OIL-BURNER.

Specification of Letters Patent. Patented Dec. 10, 1918.

Application filed May 16, 1918. Serial No. 235,017.

To all whom it may concern Be it known that I, FLAvE J. Scorr, a citizenof the United States, residing at Marshalltown, in the county ofMarshall and State of Iowa, have invented certain new and usefulImprovements in Oil-Burners; and I do declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to that class of oil burners which convert the oilinto vapor and mix it with air before combustion takes place, and theobject is to provide an extremely simple and inexpensive, yet a highlyeflicient and desirable burner of this class which may be used fornumerouspurposes.

With the foregoinggeneral object in view, the invention resides in thenovel features of construction and unique combinations of parts to behereinafter fully described and claimed, the descriptive matter beingsupplemented by the accompanying drawing which forms a part of thisspecification and in which:

Figure 1 is a side elevation of the burner;

Fig. 2 is a vertical section thereof; and

Figs. 3 and 4: are horizontal sections on the planes of the lines 33 andl-Aresped tively of Fig. 2.

In the drawing above briefly described, the numeral 1 designates ahorizontally disposed ring formed of piping and serving to vaporize thefuel, said ring having a fuel supply pipe 2 which rises verticallythereto, and a fuel outlet pipe 3 which depends from the ring, the lowerend of said pipe 3 being bent laterally and upwardly at 4 and having afuel discharge nozzle 5 disposed centrally under the ring 1. A pilot pan6 is suspended from the lateral portion a of the pipe 3 for initiallyheating said pipe so that the fuel passing therethrough will besufliciently vaporized to burn and heat the ring -1. v

Extending diametrically across and secured at its ends to the ring 1, isa horizontal bridge bar 7 upon which the top 80f a cylindrical casing 9rests at its center. The casing 9 is open at its lower end and the top 8of said casing is depressed, to form a spreader, being of substantiallyconcavoconvex formation as shown clearly in Fig. 2. Arounditsperipheral'portion, the top 8 is formed with perforations 11 andothers 12 are located in the wall of the casing immethe ring 1, down thepipe 3, and is -will be highly efiicient and desirable.

diately beneath the plane of the ring 1. A single central fastener 13 isprovided for securing the casing to the bridge bar 7 said fastenerpassing through said bar and through the center of the top 8 as shown.This arrangement is not only simple and inexpensive, but when the burneris used in a furnace for instance, so that only one side thereof isaccessible for cleaning, the entire casing may be turned upon thefastener 13 so' that the openings 11 and 12 may be cleaned throughoutthe circumference of the casing. It is also worthy of note that thedepressed top 8'forms a spreader and at the same time coacts with thebridge bar in supporting the entire casing.

In operation,the burner may be "installed wherever required and the oilis supplied by means of the pipe 2, this oil flowing throigh 1schargedfrom the-nozzle 5 in the form of vapor. This pipe 3 is initially heatedby'the priming pan 6. The vapor rising from the nozzle 5 into the casing9 mixes with air andforms a highly combustible fuel which readily burnsand produces intense heat. Considerable burning of the fuel takes placein the casing 9 and thus heats the ring 1 so that the oil passingtherethrough will be vaporized without using the pan 6 except wheninitiallyv lighting the device. The top 8 spreads the burning gases andforces them in jets through the openings Hand 12 as will be readilyunderstood from Fig; 2.

From the foregoing, taken in connection with the accompanying drawing,it will be obvious that although my invention is of extremely simple andinexpensive nature, it Since probably the best results are obtained fromthe exact construction shown and described, it is preferably followed,but within the scope of the invention as claimed. considerable latitudeis allowed for making such minor changes as occasion may dictate.

I claim;

An oil burner comprising an oil vaporizing ring disposed horizontally,an oil supply pipe rising vertically to said ring, an outlet pipedepending from said ring, and a fuel discharge nozzle below said ring towhich said outlet pipe extends; together with a horizontal bridge barextending diametrically across and secured to said ring, a casing inwhich said ring and said pipes are located, said casing being open atits lower end and having adepressed substantialiy concav0convex topresting at its center-on said bridge bar to support-the casing and 1peripheral portion of said casing havstantially as which the burningtheSpreader and a, central'fastener connecti-ng said casing top to saidbridge bar, suba-nd for the purposes set forth. 10

In. testimony whereof I have hereunto set my hand.
